Yes, they are very constitutional. The government exists to ensure the safety of the population. If that means preventing the possession of weapons with no legal or reasonable purpose, the banning of possession at all by those who cannot or will not use them safely, and the requirement of proper education and monitoring, then that is what must occur.

The Second Amendment has been selectively re-interpreted over the last 100 years or so, but not even the most fervent NRA member believes that it prohibits ANY gun control laws. Most people believe that gun control laws banning convicted criminals from owning firearms are completely reasonable. Gun opponents argue that all guns are dangerous and should be banned, while gun supporters believe that law-abiding citizens have a right to own guns. The plain text of the Second Amendment is pretty clear. The recent "Heller" Supreme Court decision, and the current case of the Chicago gun bans have changed the outlook for gun control laws, and we won't know what the end result will be for some years.
Your question asks for an opinion. My opinion is that gun control laws are based on a flawed belief that a person who will break laws regarding murder, robbery and rape will obey another law that says they may not have a gun. There are already about 20,000 Federal, State, and local gun laws on the books in the US. Gun control laws frequently do little except keep law abiding people from being able to defend themselves.
Gun laws.
The Judicial branch plays a crucial role in gun control through its interpretation of the Second Amendment and the constitutionality of gun laws. Courts adjudicate cases that challenge or uphold regulations, determining whether specific laws infringe on individuals' rights to bear arms. Landmark Supreme Court decisions, such as District of Columbia v. Heller and McDonald v. City of Chicago, have shaped the legal landscape of gun rights and restrictions. Ultimately, the Judicial branch ensures that gun control measures align with constitutional protections while balancing public safety concerns.
Most laws aren't enforced.
Some argue that gun control laws are ineffective because they primarily target law-abiding citizens, rather than criminals who obtain firearms through illegal means. Additionally, criminals can still find ways to access and use firearms even if stricter gun control measures are in place. Moreover, the effectiveness of gun control laws can vary depending on the specific policies implemented and the enforcement of those policies.
